Some states have E30 at the pumps. THOUGHTS?
#2
I am thinking I can make my own mixture of 93 and E85 to possibly get a fuel that is 30percent ethonal. I like e85 for performance but having much lower miles per tank makes it a no go for my street rx7. My car get driven and sometimes those drives are longer distance.

Yes do it. We run E20 pump in Thailand, quote a few cars over 600whp on 2 rotors with E20 pump and no aux injection. There's very little benefit going over an E60 mix, the cooling capacity and the knock limit increases are not linear to % mix. Lower e content also means less residue left behind and supposedly less breakdown of the seal oiling layer / apex seal oil.
Is it cheaper as well? Just make sure enough places have it, or you will need a solid flex fuel tune
Edit: Are you able to get E30 pump locally? Always mixing to a target is dangerous, you'll either blow it up or you'll be leaving performance on the table. You need to run a flex fuel sensor if you're mixing and matching at the pump

^^oh c’mon.
It would be best to have an ethanol sensor and ecu that can account for ethanol % variances and there’s an argument (there always is, ね〜) that 30% is all you need, but my recommendation is to shoot higher when mixing because because there is an advantage to higher % that the argument for 30% max doesn’t fully account for in a wankel turbo application imo. There are still benefits at that level over gasoline though. You need to also consider additional premix oil with an alcohol compatible oil and also “imo” an alcohol type top lube oil addition as well to guard against the “dryness” feature of alcohol fuel (~1/2 oz/gallon in addition to the premix amount).
